Abu Hurairah · The Book of the Adhan (The Call to Prayer)

"At the time of the Messenger of Allah (S.A.W) the phrases of the Adhan were said twice and the phrases of the Iqamah were said once, except that you should say: 'Qad Qamatis-Salah, Qad Qamatis-Salah (prayer is about to begin, prayer is about to begin).'"

"The final words of the Adhan of Bilal were: 'Allahu Akbar, Allahu Akbar, Allahu Akbar; La ilaha illallah (Allah is the Greatest, Allah is the Greatest, there is none worthy of worship except Allah.)'"

"I heard Mu'awiyah say: 'I heard the Messenger of Allah (S.A.W), when he heard the Mu'adhdhin, repeating what he said.'"

"I was with Mu'awiyah when the Mu'adhdhin called the Adhan. Muawiyah said what the Mu'adhdhin said, but when he said: 'Hayya 'alas-salah (come to prayer),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah);' and when he said: 'Hayya 'alal-falah (come to prosperity),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah).' After that he said what the Mu'adhdhin said,…

"The Messenger of Allah (S.A.W) said: 'Whoever says, when he hears the call to prayer: "Allahumma rabba hadhihid-da'wat it-tammah was-salat il-qaimah, ati Muahmmadan al-wasilah wal-fadilah, wab'athu maqaman mahmudan alladhi wa'adtahu (O Allah, Lord of this perfect call and the prayer to be offered, grant Muhammad the privilege (of interceding) and also the eminence, and resurrect him to the praised position that you have promised),' will be granted my intercession on the Day of Resurrection."
